Challenged by a user on Twitter to provide evidence with the cabbie’s registered taxi number and licence plate, Allen hit back that she had “both my hands full with children” and could not reach for her phone to record either.

“Whilst it is not clear whether the driver in question was an LTDA member, we take any allegation such as this extremely seriously and would condemn any cabbie who treats anyone with such disrespect and uses abusive language in this way.

“The driver in question has put their license in jeopardy with this appalling behaviour, and we would urge TfL as the regulator for our industry to undertake an investigation.”

Allen has spoken out since her video from Calais moved and angered many. She admitted in an LBC interview that she “could have chosen my words better” and instead apologised for her country’s role in the global crisis.

She said of the negative reaction to her comments: ”What they seem to have picked up on is I apologised on behalf of the nation, but it was an emotional moment I was affected by.

“Perhaps I could have chosen my words better and said: ‘I apologise for the part the country I come from has played in the situation you’re currently experiencing’ - but that was what I said and has been picked up on.

She added: “It is being used to support the xenophobic rhetoric and narrative that we are currently experiencing, especially in the mainstream press.”
